[0014] This utility model has the following beneficial effects:

[0015] This utility model designs a wireless charging power supply with good heat dissipation. Through its design, the main body of the wireless charging module charges the mobile phone, and the mobile phone is limited by magnets. A fan is installed inside the heat dissipation box. The fan draws in outside air, which enters the heat dissipation box through several air intakes. This air cools the components inside the protective shell. The heat-exchanged air is then blown out through the exhaust vents to the area below the mobile phone, promoting airflow and facilitating heat dissipation. As air enters the air intakes, a filter blocks dust, preventing dust from entering the fan and causing damage. When the filter becomes clogged... Press both handles to detach the connecting rods from the heat sink box. Move the handles to the right to remove the sealing frame and filter. After cleaning the filter, place the sealing frame into the sealing groove and release the handles. The connecting spring will move the two connecting rods away from each other, allowing the connecting rods to enter the heat sink box. This will limit the position of the protective frame and filter, making it easy to quickly disassemble and clean the filter without affecting the air intake efficiency. This device can effectively block dust from entering the air intake without affecting the air intake efficiency, thus reducing the probability of dust accumulation inside the fan and causing damage, thereby improving the heat dissipation efficiency of the device.

[0016] This utility model designs a wireless charging power supply with excellent heat dissipation. Through its design, when a mobile phone is placed on the main body of the wireless charging module, the bottom of the phone is in contact with the top of the heat sink. The heat sink absorbs the heat generated by the phone and transfers the heat to the interior of the heat sink block. The heat sink block exchanges heat with the outside air, allowing the heat to be transferred into the air, thereby reducing the phone's temperature. Several vents within the heat sink block facilitate airflow around it. When the fan inside the heat sink box is activated, outside air enters the heat sink box through the air inlet, increasing the airflow velocity in the vicinity, which further accelerates the heat dissipation speed of the heat sink block, thus accelerating the heat dissipation speed of the heat sink plate and the phone. This makes the device convenient for dissipating heat from the phone through the heat sink plate and heat sink block, further accelerating the phone's heat dissipation speed and improving the device's heat dissipation efficiency.

[0023] Reference Figures 1-4 This utility model provides a wireless charging power supply with good heat dissipation: it includes a protective shell 1, a wireless charging module body 2 fixedly mounted on the top of the protective shell 1, a heat dissipation box 3 fixedly mounted on the top of the protective shell 1, a magnet 4 fixedly mounted on the top of the heat dissipation box 3 for securing the mobile phone, several air inlets 5 inside the heat dissipation box 3, two sealing grooves 6 inside the heat dissipation box 3, a sealing frame 7 inside each of the two sealing grooves 6 for securing a filter screen 8, a filter screen 8 inside each of the two sealing frames 7 for filtering air, two sliding grooves 9 inside each of the two sealing frames 7, connecting rods 10 slidably connected inside each of the four sliding grooves 9, a connecting spring 11 fixedly mounted on one end of each of the four connecting rods 10 for pressing the connecting rods 10, one side of each of the four connecting springs 11 fixedly connected to the interior of the two sealing frames 7, movable blocks 12 fixedly mounted on the side of each of the four connecting rods 10, a handle 13 fixedly mounted on one side of each of the four movable blocks 12, and several exhaust ports 14 at the top of the protective shell 1.

[0024] As a further implementation of the above technical solution: both sealing frames 7 have fixing grooves inside, and the inside of the two fixing grooves are fixedly connected to the sides of the two filter screens 8 respectively, so that the sealing frames 7 can fix the filter screens 8.

[0025] As a further implementation of the above technical solution: the heat sink 3 has four connection holes inside, and the sides of the four connecting rods 10 respectively fit into the inside of the four connection holes, so that the heat sink 3 can limit the internal fan.

[0026] As a further implementation of the above technical solution: each of the two sealing frames 7 has two positioning holes inside, and the interior of the four positioning holes is respectively in contact with the sides of the four connecting rods 10, so that the connecting rods 10 can limit the sealing frame 7.

[0027] As a further implementation of the above technical solution: two movable grooves are opened on one side of each of the two sealing frames 7, and the interior of the four movable grooves are slidably connected to the sides of the four movable blocks 12 respectively, and the movable blocks 12 facilitate the fixing of the handle 13.

[0028] In practice: When wireless charging is needed, the phone is placed above the wireless charging module body 2, and the phone is charged through the wireless charging module body 2. The protective shell 1 has a power supply to power the wireless charging module body 2 and the fan inside the heat dissipation box 3. The phone is limited by a magnet 4. The heat dissipation box 3 has a fan. When charging begins, the fan is activated, drawing in outside air and allowing it to enter the heat dissipation box 3 through several air intakes 5. The air exchanges heat with the internal components of the protective shell 1, thus cooling the internal components and preventing overheating that could affect charging efficiency. The air after heat exchange is blown to the area below the phone through the exhaust port 14, increasing the airflow below the phone and allowing the nearby cooler air to exchange heat with the phone, thus facilitating heat dissipation. When the air enters the air intakes 5, the filter 8 blocks dust from the air, preventing dust from entering the fan and causing airflow problems. When the fan is damaged, the device's heat dissipation efficiency is improved. When the filter is clogged, press the two handles 13, which will move the two movable blocks 12 closer together, thereby moving the two connecting rods 10 closer together, causing the connecting rods 10 to detach from the heat sink box 3. At this time, move the handle 13 to the right, which will move the connecting rods 10, the sealing frame 7, and the filter 8 to the right, so that the filter 8 can be removed. After the filter 8 is cleaned, put the sealing frame 7 into the sealing groove 6, release the handle 13, and the connecting spring 11 will move the two connecting rods 10 away from each other, so that the connecting rods 10 enter the heat sink box 3, thereby limiting the connecting rods 10, thereby limiting the protective frame and the filter 8, so that the filter 8 can be quickly disassembled and cleaned without affecting the air intake efficiency of the air intake hole 5. Thus, this device can easily block the dust in the air entering the air intake hole 5 without affecting the air intake efficiency of the air intake hole 5, thereby reducing the probability of dust accumulation in the fan and causing damage, thereby improving the heat dissipation efficiency of the device.

[0029] As a further implementation of the above technical solution: the top of the heat sink 3 is provided with a fixing plate 15, the bottom end of the fixing plate 15 is fixedly connected to the top of the heat sink 3, and the fixing plate 15 facilitates the fixing of the heat sink 16.

[0030] As a further implementation of the above technical solution: a number of heat dissipation blocks 16 are fixedly provided on the top of the fixed plate 15, and a number of ventilation holes are opened in the interior of the heat dissipation blocks 16, so that the heat dissipation blocks 16 can absorb the heat of the heat dissipation plate 17.

[0031] As a further implementation of the above technical solution: a heat sink 17 is provided at the top of a plurality of heat sink blocks 16, and the bottom end of the heat sink 17 is fixedly connected to the top of the plurality of heat sink blocks 16 respectively, so that the heat sink 17 can absorb the heat of the mobile phone.

[0032] In practical implementation: When the mobile phone is placed on the wireless charging module body 2, it is attracted by the magnet 4, thus fixing the phone in place. At this time, the bottom of the phone is in contact with the top of the heat sink 17. The heat sink 17 absorbs the heat generated by the phone and transfers the heat to the heat sink 16. The heat sink 16 exchanges heat with the outside air, allowing the heat to be transferred into the air, thereby reducing the temperature of the phone. Several ventilation holes in the heat sink 16 facilitate air circulation around the heat sink 16. When the fan in the heat sink box 3 is activated, outside air enters the heat sink box 3 through the air inlet 5, which increases the airflow speed in the vicinity, further accelerating the airflow speed around the heat sink 16, thereby accelerating the heat dissipation speed of the heat sink 16, and thus accelerating the heat dissipation speed of the heat sink 17 and the phone. This makes the device convenient for dissipating heat from the phone through the heat sink 17 and the heat sink 16, thereby further accelerating the heat dissipation speed of the phone and further improving the heat dissipation efficiency of the device.
